For those who follow pop music in Asia, the problem was that Crayon Pop's new matching outfits didn't exactly seem new—they reminded people of outfits Momoiro Clover Z outfits.

Momoiro Clover Z is one of the biggest groups in Japan. They sell millions of CDs and has sung the Pokemonanime theme song. The group has been around since 2008, and the group is famous in Japan for its color-coordinated and matching uniforms, which are inspired by everything from Power Rangers outfits, pirate clothing, school clothes, and more. Part of Momoiro Clover Z's appeal is their outfits.

In South Korea, this similarity didn't go unnoticed online. According to NicoNico News, the group's management even had to come out and comment on the Christmas tree threads, pretty much explaining that if you make a Christmas tree-inspired outfit, it's going to look like this. And that, it seems, looks like a Momoiro Clover Z outfit?

But the J-pop supergroup isn't free of their own copying allegations: Earlier this year, Momoiro Clover Z was accused of stealing the work of American fashion brand IIMUAHII.
